Key result
Heart rate variability assessment in a brain-dead patient revealed residual very low frequency waves for approximately 10 minutes, likely related to residual sympathetic vasomotor activity.

May support HRV detection of residual sympathetic activity post-brain death; hypothesis-generating and leaves open need for validation.
Case Report (n=1)
HRV analysis can detect transient residual sympathetic vasomotor activity immediately following the diagnosis of brain death.
Machado et al. (2015) conducted a case report in Brain death (n=1). Heart rate variability (HRV) assessment was evaluated on Residual vasomotor activity (VLF, LF, and HF waves). Heart rate variability assessment in a brain-dead patient revealed residual very low frequency waves for approximately 10 minutes, likely related to residual sympathetic vasomotor activity.
